How should i beat the dark aeons ??

[chichi]

I beat a couple of the dark aeons with Yojimbo (Valefor and Bahamut) but then decided to raise my characters stats. I raised all their stats to the max, except for luck(couldn't be bothered fighting Earth Eater so many times) and made sure two of my characters had auto-phoenix attached-which helped a lot!
With Yojimbo, you have to fight him five separate times in the cave and you can't save between battles or it will be reset to the first encounter. He is pretty easy though if you have two characters with a ribbon and one, or better two people with auto-haste and Wakka has learned the attack reels plus 99999 damage.
Actually, a good way of getting all the equipment you need is to fight Yojimbo once and then save it. That way you fight him as many times as you need.
Also, I haven't seen anyone else write this but from memory you can fight the Magus Sisters separately. When you first encounter them, if you run away from them up Mushroom Rock Road and reach the lift at the end without them catching you, the fat one and the little one (can't remember which is which!) will get tired and stop persuing you, leaving you to only encounter the tall skinny one.
